dark matter

found this on one of the fics I read. Abnormal fics, readable

"Scientists have been arguing for centuries about whether the universe will continue expanding forever or will eventually collapse into another Big Bang. That all depends on the mass of the universe, so they've been trying to calculate it. Based on what they measure and their theories about the origin of the universe, the mass they see is less than the minimum amount they know must be there. They call the missing mass 'dark matter' because it's there but they can't see it -- it doesn't reflect light well or it's too small or it's hidden. They think some of it is slightly out of phase with the rest of the universe -- still there, but not quite visible. Of course, they're always trying to detect dark matter so they can determine what will happen sometime a few billion years in the future."

"In our minds it's usually the things we don't see that determine what happens in our heads and ultimately our lives. Some people repress bad memories, other people transfer emotions, others become fragmented personalities, most of which don't know about each other, some people act out against themselves or others. Sometimes you go a lifetime and the dark matter isn't a problem. Other times, you don't see it until it sucks you in and tears you apart. Sometimes you're lucky enough to spot it before it comes to that, or to realize what's happening before you're too far gone... Sometimes you need a little help charting it all out."
